WWW, ISWC and WebDB are the top Web conferences based on Microsoft Academic Search citation data.

Last week HCI researcher Antti Oulasvirta has an interesting post on ranking HCI conferences using the average citations per paper based on data from Microsoft Academic Search (MAS). Some of the results surprised him, including that the venerable CHI was not the top conference in this group. His ranking metric for conference significance is essentially the impact factor used for journals, a measure of the average number of citations a paper in a given journal receives in a time period. The IF metric has become widely used in the scholarly journal publication industry since it was defined by Eugene Garfield and first implemented by the company he founded, the Institute for Scientific Information.

Microsoft Academic Search provides citation and publication numbers for conferences in sixteen different subjects domains and a number of sub-domains for each. For computer science, there are 24 sub-domains including one for “World Wide Web” conferences. Following Oulasvirta, we ranked Web technology conferences using the average number of citations received in the last ten years. Starting with 68 Web technology conferences in the MAS collection (not a complete list, btw), I narrowed the set to those that had at least 100 papers in the past ten years and some papers in the past five. This resulted in 26 conferences, eliminating many series that only ran a few times or have stopped. Here are the results.

The results should only be taken as a rough estimate of conference impact. One reason is that IF is only a measure and does not take into account all aspects of scientific importance. For example, as computed here, all citations count equally, including those from high- and low-ranking sources. Another is that while Thompson-Reuters (nee ISI) journal citation data is carefully collected and curated, the Microsoft Academic Search data is the result of a largely automated process that starts with data from Bing. When I tried using the citation information from the past five years, for example, I noted that it reported 23 papers in the past five years for Adaptive Hypermedia and Adaptive Web-Based Systems. This is because the conference merged with User Modeling in 2009 to become User Modeling, Adaptation, and Personalization. Yet another shortcoming is that the MAS list of Web conferences in not complete, for example, omitting the popular ESWC, which has been running since 2004.
